The NASA Swift space telescope, which has orbited Earth for nearly 22 years, has lost control and is descending toward the planet. While most of the 1.5-ton satellite is expected to burn up upon atmospheric re-entry, experts have not ruled out the possibility that some debris could reach the surface, according to reports from LA.lv and NRA.lv.
Failed Attempts to Stabilize Descent
The telescope’s descent was accelerated by increased solar activity, which caused Earth’s upper atmosphere to expand and created greater drag on the satellite. NASA ceased scientific operations on October 20 after attempts to stabilize the spacecraft failed. NRA.lv reports that NASA had previously tasked the company Katalyst Space with a rescue mission using a robotic craft named Link. The attempt to save the apparatus with a specialized robot proved unsuccessful, as the robotic craft could not get closer than 12 to 15 kilometers to the telescope, and the robot subsequently fell to Earth in September.
Potential Debris Impact Zones
The predicted re-entry path covers broad regions, including Africa, Australia, India, Southeast Asia, Central America, and South America. Despite the wide geographic scope, both sources note that the most likely outcome is for any surviving fragments to fall into the ocean. Brad Cenko, the mission’s principal investigator, stated that while most of the apparatus will disintegrate, components made of tungsten—a metal denser than lead—are among the parts most likely to survive the heat of re-entry.
Scientific Legacy of Swift
Launched in November 2004, the Swift telescope was originally intended for a two-year mission. It ultimately operated for nearly 22 years, recording more than 2,000 gamma-ray bursts, which are among the most powerful explosions in the universe. Beyond these bursts, the telescope observed approximately 1,400 exploding stars, as well as comets, asteroids, and black holes. Swift was noted for its ability to quickly rotate toward sudden cosmic events and alert other observatories, such as the Hubble and James Webb, for follow-up study.
Safety Assessments and Future Tracking
The risk of debris causing harm to a person is estimated at approximately one in 2,100, according to TSN, as cited by LA.lv. While this probability is considered low, specialists continue to monitor the uncontrolled trajectory of the 1.5-ton object. The exact timing of the final descent remains subject to ongoing assessment by the U.S. Space Force, which has indicated that re-entry could occur within a window of a few days.
Frequently Asked Questions
While most of the structure is expected to incinerate during re-entry, components constructed from dense materials such as tungsten and certain mirror parts are the most likely to survive the high temperatures and reach the Earth’s surface.
The potential impact zone spans vast regions across multiple continents, though the high percentage of the Earth’s surface covered by water makes the ocean the most probable landing area.
